Ok so I just got gta iv yesterday for this first time ever! I got it on my ps3! I have a question now! The GTA IV i bought is 9.99 but the episodes are also 9.99! I do not really care for the stories between them i just like to free play and stuff! Can you tell me if there are the same vehicles that are in gta iv that are in gta iv Episodes of Liberty City? What are the differences! What does gta IV have that the episodes do not have other than the story of niko?
